Can\u27t You Smell That Smell? Clean Air Act Fixes for Factory Farm Air Pollution

Massive facilities that keep large numbers of livestock have overtaken small, independent farms as the primary source of meat, eggs, and dairy in the United States. These concentrated animal feeding operations ( CAFOs) compare more to industrial manufacturing operations than to traditional farms, and emit huge quantities of air pollutants that are harmful to public health, sickening people and damaging the environment. The Environmental Protection Agency ( EPA ) possesses statutorily provided tools under the Clean Air Act that it uses to regular other polluting industries. However, this article - after reviewing the rise of CAFOs, examining the threats they pose, and surveying current regulation - suggests that the EPA\u27s approach to CAFOs is grossly inadequate. The article argues that the agency, under the Clean Air Act, should regulate the emissions of hydrogen sulfide and ammonia, two pollutants for which factory farms are major sources. This approach is incomplete, however. Pollutant-based regulation is both overbroad in that it will regulate other sources of these pollutants and underbroad because CAFO air pollution includes more than just these pollutants. The EPA should therefore additionally or alternatively rely on a more thorough and flexible pollution source-specific tool, the New Source Performance Standards ( NSPS ). NSPS are analogous to the rigorous source-specific approach used to regulate CAFO water pollution under the Clean Water Act, and will provide a comprehensive antidote to the ills of modern, industrial animal agriculture

Cultural contacts and ethnic origins in Viking Age Wales and northern Britain: the case of Albanus, Britain's first inhabitant and Scottish ancestor

Albanus, an eponymous ancestor for the kingdom of Alba, provides an example of the extent to which the creation of an ethnic identity was accompanied by new ideas about origins, which replaced previous accounts. Through an analysis of the Historia Brittonum’s textual tradition and Welsh knowledge of early Roman history and medieval ethnic groups, this article establishes that Albanus was added to the Historia Brittonum in the late ninth or early tenth century as an ancestral figure for the new kingdom of Alba in northern Britain. This was potentially a result of shared political situations in Gwynedd, Alba (formerly Pictland) and Strathclyde in relation to Scandinavian power at this time, which encouraged contacts and the spread of Alba-based ideology to Gwynedd. The later development of this idea and its significance in Alba itself, Geoffrey of Monmouth's account and English claims to supremacy over Scotland are also traced

Goodwillie towers and chromatic homotopy: an overview

This paper is based on talks I gave in Nagoya and Kinosaki in August of 2003. I survey, from my own perspective, Goodwillie's work on towers associated to continuous functors between topological model categories, and then include a discussion of applications to periodic homotopy as in my work and the work of Arone-Mahowald.Comment: This is the version published by Geometry & Topology Monographs on 29 January 200
